From my understanding, it was only released under the diaclone line. Hasbro used the diaclone version for the box art and catalogue images but the blue version was never sold in Transformers packaging, only the grey version.

There are actually 3 versions of the figure in terms of color that were released in the 1980s ....silver, silver/black, and blue/silver. The silver one became the G1 toy, the silver/black one was used for the animated show, and this one became the boxart. Not very many blue Bluestreak figures exist. The silver/black one was reissued through Ehobby.
